Good evening

. This afternoon I read the forum and watched this cam for the first time - very interesting. Thanks for all the beautiful pictures! When I compared them, my impression was, there´s a breeding paire-to-be (those who shared the fish, both ringend at the right leg.) And then there seems to be another bird, maybe a new arrival, ringend on the left tarsus. Perhaps a strange idea, but is it possible that some of the scenes were no matings but attacks?
The bird which busily arranged the nest material today when I opened the cam 17:37 was ringend on the right leg. It left the nest 17:47. This one (or another one also with a ring on the right tarsus) was there when I opened the cam again 18:06. This time no work at the nest. The bird sat there and looked around very attentive. Just a bit of preening sometimes, but very short. Once it flapped its wings. 18:16 a lot of flapping; probably another eagle flew by (wing sounds).
All happened very fast. Afterwards I had a look at the video with single clicks at the “play” button (to get some kind of slow motion), and I´m quite sure
two eagles flew by 18:17:01/02. More flapping in the nest. 18:17:16 a second eagle landed (ring on the left tarsus). Both spread the wings, then they sat in the nest, the first one turned it´s back to the arrival. 18:17:54 wing sounds very nearby. “Right leg ring” turned around to “left leg ring” and spread the wings again (threatening gesture?). 18:18:06 it “jumped” in the air and disappeared. Now “left leg ring” flapped its wings - maybe a try to defend the nest he or she want´s to occupy?
18:18:11: Attack from the air to scare the intruder? Talons were visible several times very close above “left leg ring”, which left the nest 18:18:14. Immediately a second eagle, again one who was ringed on the right tarsus, landed at the nest. Again this one sat there and looked around very attentive all the time. 18:20 another bird or this bird called, an the latter left the nest.
Maybe I´m wrong with this observations and ideas, but if not it might be interesting to keep this in mind?
The video upload to YouTube was possible, but YouTube said there´s an audio/video problem. Indeed, the quality is unfortunately horrible

At my computer it´s quite normal, just a bit blurred. Think it´s because the recording was an VLC media file (.mp4). I would be glad about any idea how to convert the mp4 file into something which is more suitable

.
For the time being I´ll post some pictures.
Sorry if this posting became a bit long.Edit: Now I found Urmas´ posting. So the "intruder" with the ring on the left leg was or is the right female at this nest.
